Recently, positioning services have received considerable attention. The primary source of
the positioning error is non-line-of-sight (NLOS) propagation. To address this problem, we …

This paper presents a new collaborative location estimation method for wireless sensor
networks (WSN), referred to as an iterative tree search algorithm (I-TSA). The proposed …

In this paper, we introduce a Quantized Cramer Rao Bound (Q-CRB) method, which adapts
the use of the CRB to handle grid-based localization algorithms with certain constraints …

Connected vehicles and intelligent vehicles have been identified as key technologies for
increasing road safety and transport efficiency. This book presents and discusss the recent …

In vehicular ad hoc networks (VANETs) safety applications, vehicular position is
fundamental information to achieve collision avoidance and fleet management. Now …

A novel position location technique that requires a reduced number of scattered observation
signals is presented in this paper. This technique infers the mobile's location based on …

A method for estimating the position of a mobile station (MS) comprising the following steps:
physically moving the MS at a constant velocity v in an environment comprising S stationary …

In non-line-of-sight (NLOS) environments, the traditional optimal localization algorithm is
weak against NLOS errors and needs an accurate initial position value to guarantee the …
